To Install A Bearing/Race Assembly:
1. Select a Sleeve (parts #1 thru #4) with a diameter large enough to rest against the outer edge of the steering knuckle.
(See Figure C, and Assy. Diagram.)
2. Select a Sleeve Plate (parts #5a, #5b) that will fit snugly on the Sleeve (parts #1 thru #4) being used.
(See Figure C, and Assy. Diagram.)
3. Place a Washer (part #22) on the Sliding Screw (part #21). (See Figure C, and Assy. Diagram.)

Sleeve (parts #1 thru #4), and the opening in the vehicle's steering knuckle. (See Figure C, and Assy. Diagram.)
5. Slide the bearing assembly (race and ball bearings) on the end of the Sliding Screw (part #21).
(See Figure C, and Assy. Diagram.)
6. Select a Bushing (parts #6 thru #19) that will slide snugly through the opening in the vehicle's steering
knuckle, and place it on the end of the Sliding Screw (part #21).
NOTE: Make sure to select the Bushing that contacts the inner/outer race of the bearing and not the
ball bearings. (See Figure C, and Assy. Diagram.)

drawing the bearing assembly into the opening in the vehicle's steering knuckle. (See Figure C, and Assy. Diagram.)
